This invention relates to a wrench and more particularly to an open endmachine end wrench in which a plurality of open end machine wrench headshaving different sized jaws are employed in connection with the samehandle thereby greatly decreasing the cost of a set of such Wrenches aswell as permitting of a compact and convenient kit.

One of the objects of this invention is to provide such a handle andopen end machine wrench heads therefor, in which the heads can bequickly applied toor removed from the handle and when so applied aresecurely held to the handle and operate reliably topermit the desiredpressure to be applied to the object gripped.

A further object is to provide such an open end machine wrench which isstrong and which will stand up under the severe and constant use towhich tools of this character are subjected.

A still further aim is to provide such an open end machine wrench whichis simple and inexpensive and in which all of the more expensivemanufacturing operations are performed on the handle since only onehandle is used in connection with a large number of heads.

Another aim is to provide an open end machine wrench of this characterin which the head can be held in different positions relative to thehandle thereby permitting of its use in places where an'open end machinewrench having a head set at a fixed angle could not be employed, and inwhich such adjustment in the angularity of the head can be effectedexpeditiously and be reliably held.

Other objects are to provide such an open end machine wrench which iscompact, light' and strong, thereby permitting of its convenient use bythe mechanic.

In the accompanying drawings v Figure 1 is atop plan view of thepreferred embodiment of my invention. Figure "2 is a side view thereof.Figure 3 is a longitudinal section thereof. Figure 4 is a fragmentarybottom plan view thereof. Figure 5 is a fragmentary bottom planview of amodified form of the invention.

Similar reference numerals refer to like parts in each of the severalviews.

The preferred embodimentof my invention shown in Figs. 1-4 isconstructed as follows:

The wrench i'scomposed of a handle to one side and at one end of whichthe open end machine wrench head 16 is applied. The wrench handle 15 maybe of any suitable construction and preferably, is hollowed out onoppositesides for lightness and is provided with a hole or opening 17"at oneend so that it can be hung up whennotin use.

The opposite end 18 of the Wrench is formed tofprovide a, flat face ,19on its. underside whichface is engaged by theupper fiat face of the openend machine wrench head 16. This face ispref'erably set- ,at an angle tothe handle sothat the head is held at a. similar angle forconvenience inmanipulating the wrench;

' I The wrench head 16 comprises a pair of.

jaws 20 and a shankor neck 21 which is provided with a circularopening-or recess 2:2 which extends therethrough and receives a 75cylindrical stem 23 which stein. projects I downwardly from the flatface 19 and is formed integrally with the handle. The engag-ement ofthis stem in the opening 22 holds the head tothe stem and to prevent thehead 179 from accidentally dropping off friction means are providedwhichare constructed as fol lows: T

011 the underside of the handle in rear of the flat face 19 a transverseridge 24 is pro- 2-? vidcd which engages the rearend of the neck orshank 21 of the vV1GI1Cl1 l1.8Zld andalso houses-a spring loaded pin 25which bears against the rear end orcdge of the wrench head and therebytends to prevent it from be 59 ing mov'ed laterally except when pressureis intentionally applied to the head to remove it from the handle. Thisridge,as best-sh own in Fig. ,.4 is formed atits outer edge to pro Hvide a.v flat; vertical face or shoulder 26 in the center of which aV-shaped notch 27 is provided. To permit ofdifierent angular adjustmentsofthe wrench head, the shank 21 0f thesame .is formed to provide threegangular faces or its head relative to the handle are provided.

thereby providing five different adjustments for the same. In using thewrench it is merely necessary to slip the head over the stern at thedesired angle'and it will be securely held thereon until it is desiredto substitute the head when it may be removed laterally and anothersubstituted.

The form shown in Fig. similar to the preferred form except that thespring loaded friction pins are provided in the sten123 and bearoutwardly against the more of the opening 22 in the head. Two springpinsfil are provided in this construction and areforced outwardly by aninterposed spring 32. This form is avaliable for larger sized wrenchesWhere the size of the stem permits of housing the spring loaded pins.

Each form of my invention proi ides an open end machine wrench which iscompact, light and durable, the wrench head is easily applied and may beadjusted to the desired angularity and when so applied is securely heldagainst accidental displacement; but is readily removed; and the wrenchand particularly the wrench headscanbe produced at low cost, therebypermitting of marlceting the wrench for a low price,

I claim as my invention:

A wrench comprising a handle, a stem projecting laterally -from one sideof said handle, an open end wrench headhaving jaws and a shank, saidshank being provided with an opening adapted to fit said stem and saidshank being formedon its outer side torprovide at least three flat facesarranged at an angle to one another and forming pointed projections, anda ridge formed on said handle adjacent the outer sideot' said shank,said ridge-being formed to provide a. flat face opposing said shank andadapted to engage any of said faces on said shank and said ridge beingformed to provide V-shaped notch at the center of its flat face,saidnotch being adapted to receive any oneot the pointed pr'ojections onsaid wrench head: In testimony whereof I hereby affix my signature.
